The Swift Gamma-Ray Burst Explorer performed its first autonomous, X-ray follow-up to a newly detected GRB on 2005 January 17, within 193 s of the burst trigger by the Swift Burst Alert Telescope. While the burst was still in progress, the X-Ray Telescope (XRT) obtained a position and an image for an uncataloged X-ray source simultaneously with the gamma-ray observation. The XRT observed flux during the prompt emission was 1.1 × 10-8 ergs cm-2 s-1 in the 0.5-10 keV energy band. The emission in… Expand
GRB 050713A: High-Energy Observations of the Gamma-Ray Burst Prompt and Afterglow Emission
Swift discovered GRB 050713A and slewed promptly to begin observing with its narrow-field instruments 72.6 s after the burst onset, while the prompt gamma-ray emission was still detectable in theExpand
The Early X-Ray Emission from GRBs
Observations of the early X-ray emission for a sample of 40 gamma-ray bursts obtained using the Swift satellite, for which the narrow-field instruments were pointed at the burst within 10 minutes of the trigger, show that theX-ray light curve can be well described by an exponential that relaxes into a power law.

GRB 061121: Broadband spectral evolution through the prompt and afterglow phases of a bright burst
Swift triggered on a precursor to the main burst of GRB 061121 (z = 1.314), allowing observations to be made from the optical to gamma-ray bands. Many other telescopes, including Konus-Wind,Expand
Swift Observations of GRB 070110: An Extraordinary X-Ray Afterglow Powered by the Central Engine
We present a detailed analysis of Swift multiwavelength observations of GRB 070110 and its remarkable afterglow. The early X-ray light curve, interpreted as the tail of the prompt emission, displaysExpand
Physical Processes Shaping Gamma-Ray Burst X-Ray Afterglow Light Curves: Theoretical Implications from the Swift X-Ray Telescope Observations
With the successful launch of the Swift Gamma-Ray Burst Explorer, a rich trove of early X-ray afterglow data has been collected by its onboard X-Ray Telescope (XRT). Some interesting features areExpand
The unique observing capabilities of the Swift x-ray telescope
The XRT is a sensitive, autonomous X-ray imaging spectrometer onboard the Swift Gamma-Ray Burst Observatory. The unique observing capabilities of the XRT allow it to autonomously refine the Swift BATExpand
Evidence for a Canonical Gamma-Ray Burst Afterglow Light Curve in the Swift XRT Data
We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts (GRBs) well observed by the Swift X-Ray Telescope (XRT). The early X-ray afterglows show a canonicalExpand
Relationship between pulse width and energy in GRB 060124: from X-ray to γ-ray bands
GRB 060124 is the first event that both prompt and afterglow emission were observed simultaneously by the three Swift instruments. Its main peak also triggered Konus-Wind and HETE-II. Therefore,Expand
Reflections on Swift from the early years
Abstract The provenance of Swift lies with earlier discoveries of Gamma Ray Burst (GRB) phenomena, starting with the serendipitous discovery of GRBs by the Vela nuclear-test-ban-treaty monitoringExpand
Shallow Decay of Early X-Ray Afterglows from Inhomogeneous Gamma-Ray Burst Jets
Almost all the X-ray afterglows of γ-ray bursts (GRBs) observed by the Swift satellite have a shallow decay phase in their first few thousand seconds. We show that in an inhomogeneous-jet modelExpand


The Discovery of the Optical and Near-IR Afterglows of the First Swift Gamma-Ray Bursts

Afterglow Emission from Naked Gamma-Ray Bursts
We calculate the afterglow emission for gamma-ray bursts (GRBs) going off in an extremely low density medium, referred to as naked bursts. Our results also apply to the case where the external mediumExpand
An unexpectedly rapid decline in the X-ray afterglow emission of long γ-ray bursts
‘Long’ γ-ray bursts (GRBs) are commonly accepted to originate in the explosion of particularly massive stars, which give rise to highly relativistic jets. Inhomogeneities in the expanding flow resultExpand
We present a comprehensive sample of all gamma-ray burst (GRB) afterglows with known distances, and we derive their conical opening angles based on observed broadband breaks in their light curves.Expand
